Middelgrundsfortet

Middelgrundsfortet is a big piece of land in Denmark that is surrounded by water. It is like a small island with a bunch of buildings on it. People used to use it a long time ago for military things, like keeping enemies away from the country. But now, people use it for different things, like a place for boats to stay and for people to explore. It is kind of like a little secret island that people like to visit.
